HEATING-STOVE.

, comprises a combustion chamber and a superposed heating chamber which are connected and supported together from the top of the downwardly extended flues or pipes, the latter thus serving practically in the place of legs or other usual form of support.

The details of construction, arrangement and combination of parts are as hereinafter described and illustrated in the accompanying drawing, in which Figure 1 is an end view of my improved stove a portion being broken away to show a flue-cleaner. Fig; 2 is a side view. Fig. 3 is mainly a vertical'transverse section. Fig. 4 is a vertical central longitudinal section of the stove.

1 indicates an oval combustion chamber, and 2 a cylindrical heating chamber, the same being connected by a flue or passage 3. The top of the heating chamber 2 is provided with two short vertical pipes 4 which connect with the curved top portions of pipes 5 having an inverted U-shape, the legs of the same extending down on each side of the chambers 1, 2, and resting u on the floor, or other horizontal base, so t at bothchambers 1- and 2 are supported clear of the latter. Removable caps 6 having enlarged heads are a plied to the lower ends of the pipes 5, as s own. The latter thus constitute legs or vertical supports for chambers 1, 2. in practice, the sides of the combustion chamber 1 are permanently attached to the pipes 5', in order to hold the latter rigidly in place. The U pipes 5 constitute down-draft flues, and their lower ends communicate by upwardly inclined pipes 7 with the legs 8 of a vertical U- shape up-draft ipe which is arranged between and equidistant from the pipes 5. A collar or short escape pipe 9 is arranged at the curved top of pipe 8, for attachment of a pipe (not shown) leadingto a chimney or into the air. Thus unlike pipes 5, the pipe 8 has Specification of Letters Patent. Application filed March 27,1907. Serial No. 364,778.

no direct connection with the heating chamber 2.

The heating chamber 1 is rovided with a i grate 10 arranged horizonta ly and with an end door 11 for introduction of the fuel and another door 12 for removal of ashes.

Within said chamber and a short distance below the top passage 3 leadin into the heating chamber 2, is located a ba e plate 13, see Fig. 3, the same serving to prevent the direct passage of the heated products of combustion from the lower chamber 1 into the upper one. The latter is traversed from end to end by a large pipe 15, which is arranged concentrically and open at each end. Air has thus free passage through the pipe or drum 15 whereby the heating surface of the chamber 2 is greatly increased, and a receptacle is provided for plates or dishes requiring to be warmed.

The course of products of combustion from chamber 1 is indicated by arrows, it being around and over the baffle-plate 13 through passage 3 into chamber 2, thenaround pipe 14 and into short pipes 4 and thence down the U pipes 5 to the lower ends of the same, whence they pass by inclined pipes 7 into the up-draft pipe 8.

By the construction of the body of the stove, that is to say, chambers 1, 2, in the manner described, I provide a relatively large heating surfacewhich is greatly extended by. arrangement of the down-draft pipes 5, their trans verse connections 7 and the up-draft ipes 8, and at the same time the pipes 5 perorm the added function of le s or supports for the body of the stove, whic 1 is very light and easily portable.

The fines or pipes 5 are provided at the top with short vertical extensions 5 and removable caps are applied thereto to provide for cleaning the curved upper portions of said pipes. Slidable flue-cleaners 14, consisting of wire coils are arranged in the legs of ipes 5, see Figs. 1 and 3 and having vertica eX- tensions or rods 14 that project through and above the upper portions of the pipes. It is obvious that caps or hollow feet 6 serve as receptacles of soot and ashes accumulated in the pipes 5, and the same may be detached from time to time, as re uired. to discharge their contents. Remova le caps 8 are also provided for pipes 8. While the chambers 1 and2 are preferably oval and cylindrical in shape respectively they may, of course, have other forms.

I claim 1. The improved heating stove comprising a combustion chamber, and a superposed heating chamber, the same having connecting passages and one dependingv from the' Other, two pairs of down draft pipes connected with the top of the heating chamber and extending below the combustion chamber so as to serves as legs for the stove roper, and an up-draft pipe connecting wit such downdraft pipes, substantially as described.

2. The improved heating stove comprising a heating chamber, a combustion chamber supported from and below said heating chamber, and the two having a connecting passage, a series of inverted U shape down. draft pipes connected with the top of the heating chamber and extending below the combus- -tion chamber whereby the; are adapted to serve also as legs for the stove proper, a U- shape up-draft pipe arranged between the down-draft pipes and connected with the same as shown and described.

3. In a heating stove the combination with down-draft pipes, and a heating chamber connected with the upper ends of said pipes and supported therefrom, of a combustion chamber attached to and de )ending from the heating chamber, and a ba 'le-plate arranged lengthwise in the combustion chamber a short distance below the passage leading into the heating chamber above, as and for the purpose specified.
